During vermicomposting, decomposition of organic matter is mostly carried out by the aerobic microbes, facilitated by the earthworms. Light, an important ecological factor can penetrate up to 3-4 cm into surface soil or organic substrates and therefore is expected to influence the biological function of microbes during decomposition. This study reports the effect of low intensity colour lights on microbial population and exoenzyme activities along with changes in certain soil chemical parameters such as pH and organic carbon in semi-decomposed organic substrate (cattle dung) inoculated with the earthworm Eudrilus eugeniae over an incubation period of 42 days. | Microbial population dynamics and exoenzyme activities in semidecomposed organic substrate exposed to low intensity colour lights during vermicomposting
